Well, well, look at this from Engadget:
The original plan was to offer mildly subsidized prices of $399 and $499 for the 16GB and 32GB versions of the iPhone 3G S to AT&T customers who weren’t currently “upgrade eligible,” but the carrier’s having a change of heart, ostensibly in response to… you know, people wanting to pay less. The new plan is to let anyone with an upgrade date in the months of June, July, August, or September get in on the fully discounted $199 / $299 price points, which should cover a good number of existing 3G owners.
Including this 3G owner, I hope.
